Autonics SR1-1425-N Solid State Relay 25A AC Output

Autonics SR1-1425-N is a single-phase solid-state relay (SPST-NO) from the SR1 family designed for panel mounting with a detachable heatsink. It accepts a DC control signal in the 4–30 V range to switch a 48–480 VAC load, delivering up to 25 A of load current through a Form A (SPST-NO) output. With screw-type mounting, it is intended for compact electrical enclosures and can be used to switch heating elements, lighting, or small motors in automation panels where silent, fast switching is beneficial. The device is specified for operation from −30°C to 80°C and employs zero-voltage switching to minimize switching transients when energizing AC loads. The model SR1-1425-N is part of Autonics’ SR1 family featuring detachable heatsink configurations, allowing heat dissipation to be managed separately from the control module. The 25 A rating and 48–480 VAC output define its suitability for moderate-load AC switching in industrial controls and machine automation, offering a robust, solid-state alternative to mechanical relays in demanding environments.
